Hello, I am finally plugging my w/b numbers into foreflight and I am stumped on one of the setup pieces. It is asking me for Forward and Aft CG limits in inches and pounds. Of course I have the inches part, but not pounds. Anyone know what or how to calculate that? surely it isn't just 1800 right?..

Yea, I thought I knew what it wanted but I was wrong. Need to know the Forward CG limits inches and lbs and Aft CG limits inches and lbs. I can't get mine to come out correct...

It's confusing, but I figured it out on our most recent plane (the Tundra). There are four points that define the square box. Each needs two coordinates - a weight and a distance from the datum. So you need a forward distance and then the empty and gross weights, and the aft distance and the empty and gross weights.

Sportys has a pretty detailed tutorial on setting this up.

The way I did it was to use gross weight for the top and empty weight for the bottom of the box.
